本文介绍了if/else vs 三元运算符的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

考虑到评估时间，以下两个是等价的吗?

Considering the evaluation time, are following two equivalent?

if(condition1)
{
    //code1
}
else
{
    //code2
}

<代码>条件 1 ?代码1:代码2

或者它们只是在语法上不同?

Or they are just syntactically different?

区别在于后一个站可以根据条件返回一个值.

The difference is that the latter station can be used to return a value based on a condition.

例如，如果您有以下语句:

For example, if you have a following statement:

if (SomeCondition())
{
    text = "Yes";
}
else
{
    text = "No";
}

使用三元运算符，您将编写:

Using a ternary operator, you will write:

text = SomeCondition() ? "Yes" : "No";

注意第一个示例如何根据条件执行语句，而第二个根据条件返回值.

Note how the first example executes a statement based on a condition, while the second one returns a value based on a condition.
